July 21, -- Just over a year ago actor David Carradine died a seedy death, hanging by a drapery cord in the cramped closet of a Bangkok hotel room. Now, his ex-wife says she believes the year-old "Kung Fu" actor was murdered. Authorities ruled that Carradine had accidentally suffocated in a lone sex practice known as autoerotic asphyxiation , but his fourth wife, Actress Marina Anderson , claims in a new book that the actor "never flew solo" and the autopsy and other details of his death "just don't fit. Anderson, who was married to Carradine from to , admits that her husband's kinky sex life -- a penchant for bondage and being choked to the point of orgasm -- was no surprise, ultimately destroying their marriage and leading to his death. That didn't fit the scenario. David liked participation.
